Southern Pacific
4294 (4-8-8-2)

SP 4294 is an "Articulated
Consolidation" (2-8-8-2) built by Baldwin in 1944 as a cab-forward
to spare crews the effects of riding behind the stack through tunnels and
long snow sheds covered with snow. Notice that the cylinders are still behind
the drivers. The locomotive is a simple articulated, meaning that all four
cylinders are high-pressure. Some articulateds built by Baldwin for Southern
Pacific before 1930 were compound locomotives with two high-pressure and
two low-pressure cylinders. These compound locomotives were later converted
to simple articulated engines. SP 4294 weighs 657,900 lbs. and has 63"
drivers and 24" x 32" cylinders. It is in the California State
Railroad Museum, Sacramento, California.
